Practical Method to Estimate Foundation Stiffness for Design of Offshore Wind Turbines

, 2020
Offshore wind turbine structures (OWTs) are dynamically sensitive due to their shape and form (slender column supporting a heavy rotation mass) and also due to the different forcing functions (wind, wave, and turbine loading) acting on the structures ...

Experimental and computational aeroelastic damping of an Offshore Wind Turbine on a monopile foundation

, 2012
In this study, Operational Modal Analysis (OMA) is used to identify the natural frequencies and damping values of the modes of an Offshore Wind Turbine (OWT) present in the response due to the stochastic excitation of ambient loads.

A new model for fatigue load sequence effects in offshore wind turbine substructures and its implications for design life

, 2018
Measurements at Offshore Wind Turbine (OWT) substructures show that typical loading patterns include overloads, underloads, and shifts in mean stress cycles, due to the everchanging wind direction.
